Mikoyan Project 1.44
The Mikoyan Project 1.44/1.42 (russian: link=no, Микоян МиГ-1.44; NATO reporting name: Flatpack) was a multirole fighter technology demonstrator developed by the Mikoyan design bureau. It was designed for the Soviet Union's MFI (''Mnogofunksionalni Frontovoy Istrebitel'', "Multifunctional Frontline Fighter") project for the I-90 ("1990s fighter") program, the answer to the U.S.'s Advanced Tactical Fighter (ATF). The MFI was to incorporate many fifth-generation jet fighter features such as supermaneuverability, supercruise, and advanced avionics, as well as some degree of radar signature reduction. The design's development was a protracted one, characterised by repeated and lengthy postponements due to a chronic lack of funds after the collapse of the Soviet Union; the MiG 1.44 made its maiden flight in February 2000, nine years behind schedule, and was cancelled later that year. The MFI project was replaced by the more modern and affordable PAK FA program, which res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration.

Dissolution Of The Soviet Union
The dissolution of the Soviet Union, also negatively connoted as rus, Разва́л Сове́тского Сою́за, r=Razvál Sovétskogo Soyúza, ''Ruining of the Soviet Union''. was the process of internal disintegration within the Soviet Union (USSR) which resulted in the end of the country's and its federal government's existence as a sovereign state, thereby resulting in its constituent republics gaining full sovereignty on 26 December 1991. It brought an end to General Secretary Mikhail Gorbachev's (later also President) effort to reform the Soviet political and economic system in an attempt to stop a period of political stalemate and economic backslide. The Soviet Union had experienced internal stagnation and ethnic separatism. Although highly centralized until its final years, the country was made up of fifteen top-level republics that served as homelands for different ethnicities. By late 1991, amid a catastrophic political crisis, with several republics alr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Five-year Plans Of The Soviet Union
The five-year plans for the development of the national economy of the Union of Soviet Socialist Republics (USSR) ( rus, Пятилетние планы развития народного хозяйства СССР, ''Pyatiletniye plany razvitiya narodnogo khozyaystva SSSR'') consisted of a series of nationwide centralized economic plans in the Soviet Union, beginning in the late 1920s. The Soviet state planning committee Gosplan developed these plans based on the theory of the productive forces that formed part of the ideology of the Communist Party for development of the Soviet economy. Fulfilling the current plan became the watchword of Soviet bureaucracy. Several Soviet five-year plans did not take up the full period of time assigned to them: some were pronounced successfully completed earlier than expected, some took much longer than expected, and others failed altogether and had to be abandoned. Altogether, Gosplan launched thirteen five-year plans. The initial fiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Research And Development
Research and development (R&D or R+D), known in Europe as research and technological development (RTD), is the set of innovative activities undertaken by corporations or governments in developing new services or products, and improving existing ones. Research and development constitutes the first stage of development of a potential new service or the production process. R&D activities differ from institution to institution, with two primary models of an R&D department either staffed by engineers and tasked with directly developing new products, or staffed with industrial scientists and tasked with applied research in scientific or technological fields, which may facilitate future product development. R&D differs from the vast majority of corporate activities in that it is not intended to yield immediate profit, and generally carries greater risk and an uncertain return on investment. However R&D is crucial for acquiring larger shares of the market through the marketisation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commonality
In aviation, fleet commonality is the economic and logistic benefits of operating a standardized fleet of aircraft that share common parts, training requirements, or other characteristics. Different types of commonality Commonality policies may be defined in a variety of ways, depending on the operator: * for civilian aircraft: ** By model, same generation (e.g. Boeing "Next Generation" 737-700, 737-800, and 737-900) ** By model, different generations (e.g. Boeing's "Next Generation" 737-700 and 737 MAX-7) ** By family (e.g. Boeing 737) ** Between families (e.g. deck, between Boeing 767-400ER, 777 and 737 NG) ** By manufacturer (e.g. Boeing) ** By engine (e.g. Rolls-Royce RB211 The Rolls-Royce RB211 is a British family of high-bypass turbofan engines made by Rolls-Royce. The engines are capable of generating of thrust. The RB211 engine was the first production three-spool engine, and turned Rolls-Royce from a sign ...) ** Any combination of the above * for militar ...

Post-PFI Soviet/Russian Aircraft Projects
The Soviet post-PFI projects refer to several Soviet and Russian Air Force projects initiated to replace the PFI-era aircraft. History In 1969, the Soviet Union became aware of the existence of the United States' "teen"-series of aircraft, including the Grumman F-14 Tomcat, McDonnell Douglas F-15 Eagle, General Dynamics F-16 Fighting Falcon and McDonnell Douglas F/A-18 Hornet. In response, the Soviets initiated the ''Perspektivnyi Frontovoy Istrebitel'' ("Perspective Frontline Fighter") -abbreviated as PFI - project to develop a multirole fighter aircraft capable of countering the new generation of U.S. aircraft. The PFI project then branched into two projects, the ''Tyazholy Perspektivnyi Frontovoy Istrebitel'', "Heavy Perspective Frontline Fighter" (TPFI) and the ''Lyogkiy Perspektivnyi Frontovoy Istrebitel'', "Light Perspective Frontline Fighter" (LPFI). The goal of the TPFI project was to develop a fighter capable of long-range flight, primarily to intercept hostile airc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multirole Combat Aircraft
A multirole combat aircraft (MRCA) is a combat aircraft intended to perform different roles in combat. These roles can include air to air combat, air support, aerial bombing, reconnaissance, electronic warfare, and suppression of air defenses. Definition The term "multirole" was originally reserved for aircraft designed with the aim of using a common airframe for multiple tasks where the same basic airframe is adapted to a number of differing roles. The main motivation for developing multirole aircraft is cost reduction in using a common airframe. More roles can be added, such as aerial reconnaissance, forward air control, and electronic-warfare aircraft. Attack missions include the subtypes air interdiction, suppression of enemy air defense (SEAD), and close air support (CAS). Multirole has also been applied to one aircraft with both major roles, a primary air-to-air combat role, and a secondary role like air-to-surface attack. However, those designed with an emph ...

Sukhoi Su-27
The Sukhoi Su-27 (russian: Сухой Су-27; NATO reporting name: Flanker) is a Soviet-origin twin-engine supermaneuverable fighter aircraft designed by Sukhoi. It was intended as a direct competitor for the large US fourth-generation jet fighters such as the Grumman F-14 Tomcat and McDonnell Douglas F-15 Eagle, with range, heavy aircraft ordnance, sophisticated avionics and high maneuverability. The Su-27 was designed for air superiority missions, and subsequent variants are able to perform almost all aerial warfare operations. It was designed with the Mikoyan MiG-29 as its complement. The Su-27 entered service with the Soviet Air Forces in 1985. The primary role was long range air defence against American SAC Rockwell B-1B Lancer and Boeing B-52G and H Stratofortress bombers, protecting the Soviet coast from aircraft carriers and flying long range fighter escort for Soviet heavy bombers such as the Tupolev Tu-95, Tupolev Tu-22M and Tupolev Tu-160.

Government Of The Soviet Union
The Government of the Soviet Union ( rus, Прави́тельство СССР, p=prɐˈvʲitʲɪlʲstvə ɛs ɛs ɛs ˈɛr, r=Pravítelstvo SSSR, lang=no), formally the All-Union Government of the Union of Soviet Socialist Republics, commonly abbreviated to Soviet Government, was the executive and administrative organ of state in the former Soviet Union. It had four different names throughout its existence; Council of People's Commissars (1923–1946), Council of Ministers (1946–1991), Cabinet of Ministers (January – August 1991) and Committee on the Operational Management of the National Economy (August–December 1991). It also was known as Workers-Peasants Government of the Soviet Union. The government was led by a chairman, most commonly referred to as " premier" by outside observers. The chairman was nominated by the Central Committee of the Communist Party of the Soviet Union (CPSU) and elected by delegates at the first plenary session of a newly elected Supreme Sovi ...

Lockheed Martin F-22 Raptor
The Lockheed Martin F-22 Raptor is an American single-seat, twin-engine, all-weather stealth tactical fighter aircraft developed for the United States Air Force (USAF). As the result of the USAF's Advanced Tactical Fighter (ATF) program, the aircraft was designed as an air superiority fighter, but also has ground attack, electronic warfare, and signals intelligence capabilities. The prime contractor, Lockheed Martin, built most of the F-22's airframe and weapons systems and conducted final assembly, while Boeing provided the wings, aft fuselage, avionics integration, and training systems. The aircraft first flew in 1997 and was variously designated F-22 and F/A-22 before it formally entered service in December 2005 as the F-22A. Although the USAF had originally planned to buy a total of 750 ATFs, the program was cut to 187 operational aircraft in 2009 due to high costs, a lack of air-to-air missions due to the focus on counterinsurgency operations at the time of production, ...

Stealth Aircraft
Stealth aircraft are designed to avoid detection using a variety of technologies that reduce reflection/emission of radar, infrared, visible light, radio frequency (RF) spectrum, and audio, collectively known as stealth technology. The F-117 Nighthawk was the first operational aircraft specifically designed around stealth technology. Other examples of stealth aircraft include the B-2 Spirit, the B-21 Raider, the F-22 Raptor, the F-35 Lightning II, the Chengdu J-20, and the Sukhoi Su-57. While no aircraft is totally invisible to radar, stealth aircraft make it more difficult for conventional radar to detect or track the aircraft effectively, increasing the odds of an aircraft successfully avoiding detection by enemy radar and/or avoiding being successfully targeted by radar guided weapons. Stealth is the combination of passive low observable (LO) features and active emitters such as low-probability-of-intercept radars, radios and laser designators. These are usually com ...

Supermaneuverability
Supermaneuverability is the capability of fighter aircraft to execute tactical maneuvers that are not possible with purely aerodynamic techniques. Such maneuvers can involve controlled side-slipping or angles of attack beyond maximum lift. This capability was researched beginning in 1975 at the Langley Research Center in the United States, and eventually resulted in the development of the McDonnell Douglas F-15 STOL/MTD as a proof of concept aircraft. The Saab 35 Draken was another early aircraft with limited supermaneuverable capabilities. In 1983, the MiG-29 and in 1986, the Sukhoi Su-27 were deployed with this capability, which has since become standard in all of Russia's fourth- and fifth-generation aircraft. There has been some speculation, but the mechanism behind the supermaneuverability of the Russian-built aircraft has not been publicly disclosed. However, post-stall analyses have been increasingly used in recent years to advance maneuverability via the use of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
